Thysanotus teretifolius

Thysanotus teretifolius is a tufted perennial herb with a small rootstock and fibrous roots. It has up to ten perennial linear, terete, more or less striated leaves up to 120–200 mm (4.7–7.9 in) long and 1.0–1.5 mm (0.039–0.059 in) wide. The flowers are borne in an umbel with ten to fifteen flowers on a pedicel 11–12 mm (0.43–0.47 in) long. The perianth segments are 11–12 mm (0.43–0.47 in) long, the sepals narrowly lance-shaped, about 3 mm (0.12 in) wide, and the petals elliptic, 6–7 mm (0.24–0.28 in) wide, with a fringe about 4 mm (0.16 in) long. There are three stamens, the anthers about 5–6 mm (0.20–0.24 in) long and curved, the style curved and bent sideways, about 5–6 mm (0.20–0.24 in) long. Flowering occurs from September to November.

This species of Thysanotus grows in sandplain vegetation in mallee eucalypts, usually in deep sandy soils, from near Northampton to near Mount Lesueur and south-east to Wongan Hills, in the Avon Wheatbelt, Geraldton Sandplains and Swan Coastal Plain bioregions of south-western Western Australia.
